Docker service not starting

Hi, I am new to Docker, and basically only need it to run a particular programme shipped as a docker container… But I am having trouble with it, because I can’t start the docker service (I am using Ubuntu 16.04).
This is the problem I have:

● docker.service - Docker Application Container Engine
   Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)
   Active: inactive (dead) (Result: exit-code) since Fri 2018-01-19 14:15:34 GMT; 6s ago

Thanks, hope this is something simple!
